Hi,

@Bodigrim is working on a patch (https://phabricator.haskell.org/D4212) to fix #14170.

The build fails because of interface file errors: "bad interface file" for GHC.Natural and "failed to load interface" for GHC.Types.

I suspect it is a wired-in module build ordering issue but I haven't been able to help fixing it. If anyone with more insights could help it would be much appreciated!

Can you paste the full error? What module is failing to compile? Which definition is it loading the interface for?

Cheers,

- Ben

Hmm, I'm afraid that's not particularly illuminating. It would be helpful to see the output from -ddump-if-trace as this will tell you why GHC is trying to load this interface file. Cheers, - Ben
